The effects of off‐centered ladle streams on fluid flow of liquid steel in a two‐strand slab tundish were studied using water modelling techniques and particle image velocimetry (PIV) measurements. Fluid flow in an off‐centered ladle stream was compared with a centered ladle stream. In a centered position the proposed arrangement (turbulence inhibitor plus dams) yields higher fractions of plug flow than the current arrangement (baffles). This effect is stronger at the high casting rate. An off‐centered position increases dead volumes at a low casting rate of 1.7 t/min. At the high casting rate of 3.8 t/min, effects of the off‐centered position are decreased although the TI‐D arrangement always renders better flow characteristics. Velocity fields determined with PIV measurements, demonstrated that the TI‐D arrangements provide the fluid with a plug flow characteristic.
